At 65-and-a-half years previous, I’m quickly approaching retirement age (for women and men of my classic, it’s 66).

Whereas I’m glad to proceed doing what I’m doing (writing, making TV documentaries and podcasts), plenty of my pals are retiring — and most appear content material with their new, much less prosperous however extra relaxed lives.

It clearly relies on your circumstances, however retirement clearly fits many people. A survey of 300,000 individuals by the Workplace for Nationwide Statistics in 2016 discovered that ranges of ‘life satisfaction’ and ‘happiness’, which have been lowest in these aged between 45 and 59, peaked between the ages of 65 and 79, then slowly declined.

In order that’s one thing to look ahead to should you haven’t but hit your 60s.

Your persona can be key to how a lot you take pleasure in retirement.

In a current survey by Kasetsart College in Thailand, greater than 2,000 British retirees, aged 50 to 75, have been requested to do a persona take a look at and likewise price their stage of life satisfaction

In a current survey by Kasetsart College in Thailand, greater than 2,000 British retirees, aged 50 to 75, have been requested to do a persona take a look at and likewise price their stage of life satisfaction.

Those that have been rated ‘conscientious’ or ‘agreeable’ loved retirement most, whereas extroverts struggled. The researchers stated that is in all probability as a result of extroverts miss the social contact you get from working.

However having fun with your retirement additionally relies on having sufficient cash and being in affordable well being.

I’ve been pondering rather a lot about wholesome ageing not too long ago as I’m at present making a TV sequence on super-agers — individuals of their 70s and 80s who’ve the brains and our bodies of these many years youthful.

I’ve spent quite a lot of time speaking to scientists in regards to the ageing course of and why some individuals appear to age a lot slower than others.

What’s notably fascinating is the work being achieved on ‘epigenetic’ clocks: these are exams used to measure your organic age — how previous your physique actually is, not simply what it says in your passport.

The standard view of ageing is that it’s brought on by a gradual build-up of injury at a mobile stage.

Similar to a automotive, bits of us get damaged or put on out. The issue is that it’s tough to place a quantity on this.

An epigenetic clock take a look at, as an alternative, measures so-called DNA methylation ranges: the extent to which particular molecules, known as methyl teams, have latched on to the DNA in your cells.

You’ll be able to consider methyl teams as a bit like barnacles attaching themselves to the hull of a ship and slowing it down.

Our methyl group ranges are inclined to rise in a really exact manner as we become older. The epigenetic clock take a look at is a robust predictor of wholesome ageing and life expectancy.

In a research in 2016, researchers on the College of California Los Angeles (UCLA) examined blood samples collected from greater than 13,000 individuals earlier than their deaths. Utilizing the epigenetic clock take a look at, they have been in a position to predict their lifespans with a excessive diploma of accuracy.

Extra not too long ago, the identical scientists confirmed that this epigenetic clock take a look at can predict the organic age and life expectancy of all types of various animals, from elephants to kangaroos, rhinos and goats.

You’ll be able to truly purchase epigenetic clock exams on-line, however their actual worth lies in measuring the effectiveness of anti-ageing therapies — the thought is you’d take the take a look at earlier than an intervention, then after, to see if it’s made any distinction.

Though it sounds macabre, one of the crucial promising present anti-ageing therapies includes being infused with younger blood.

A 2020 research within the journal Science confirmed that giving blood from younger, lively mice to previous mice made the older mice smarter, extra alert, and led to the expansion of recent mind cells. In one other research, revealed not too long ago as a pre-print (which means it’s not but been formally accepted by a journal), the UCLA researchers confirmed that this type of blood transfusion additionally improved older mice’s grip energy and rejuvenated their hearts, livers and reminiscences. Amazingly, it additionally halved their organic age.

Analysis is now beneath option to discover out precisely what it’s in younger blood that has these exceptional, rejuvenating results. But it surely’s not but being utilized in people.

Scientists are additionally utilizing the epigenetic clock to check on a regular basis medicines for anti-ageing properties.

As an example, analysis revealed within the journal Cell in 2019 confirmed that taking a cocktail of frequent medicine might reverse individuals’s organic age.

Within the research, 9 wholesome male volunteers aged 50 to 65 took a mixture of a development hormone, metformin (generally used for sort 2 diabetes) and a drug known as DHEA (an artificial model of a hormone our our bodies naturally produce and that helps within the manufacturing of intercourse hormones comparable to testosterone and oestrogen).

After a 12 months, not solely had their organic ages dropped by a mean of two-and-a-half years, however their immune programs confirmed clear indicators of being rejuvenated. This was a small trial, so you may’t learn an excessive amount of into it, however a a lot bigger research is now beneath manner.

We’re not going to be guzzling anti-ageing medicine or infusing ourselves with younger blood any time quickly, however there are some life-style modifications which were proven to make a distinction.

In a research final 12 months within the journal Ageing, 43 males have been requested to both observe an eight-week life-style programme — which included intermittent fasting, half-hour of brisk train a day and twice-daily respiration workouts to scale back stress — or act as a management.

After simply two months, the lads on the programme decreased their organic age by 1.96 years on common, whereas the management group had bought a bit older.

So in case your job is stressing you out and retirement or going part-time isn’t an possibility, then that is perhaps one thing it’s best to take into account. It might purchase you extra time.
